Hong:
I used 3.3-p2 but I was able to reproduce this error with 3.3-p5 as well. I
ran it with one MPI process. I got the same error,

Using one MPI process, this error goes away when I make a temporary matrix
and store the result of the first multiplication in it as in:
ierr = MatLoad(ProjR,viewer);CHKERRQ(ierr);
ierr = PetscViewerDestroy(&viewer);CHKERRQ(ierr);
ierr =
MatMatMult(*KFullMat,ProjR,MAT_INITIAL_MATRIX,PETSC_DEFAULT,&TempMat);CHKERRQ(ierr);
ierr = MatDuplicate(TempMat,MAT_COPY_VALUES,&TempMat2); CHKERRQ(ierr);
ierr =
MatMatMult(ProjLT,TempMat2,MAT_INITIAL_MATRIX,PETSC_DEFAULT,&KProj);
CHKERRQ(ierr);
ierr = MatDestroy(&TempMat);CHKERRQ(ierr);
ierr = MatDestroy(&TempMat2);CHKERRQ(ierr);
If I run more than one process the error returns.

If it matters I am using Petsc through SlepC-3.3-p3
